Aims and objectives We aimed to audit the management and maternal and fetal outcomes of women with gestational diabetes.

Methods We did a retrospective collection of data from all women with gestational diabetes who delivered between 1^st January 2010 and 30^th June 2010. Data was collected from electronic databases and clinical notes. Diagnosis of GDM was made using WHO GTT either in the index pregnancy or a previously affected pregnancy. Women with HbA1c <6.1 throughout pregnancy were considered as having good control and women with last HbA1c> 6.1 were said to have suboptimal control.

Results A total of 154 women with gestational diabetes delivered in the above period. Of these 114 (73%) were newly diagnosed GDM. Overall incidence of macrosomia was 5% for birthweight > 4kg. Three (2%) of the babies had shoulder dystocia at birth with no neonatal injuries. Three (2%) babies were admitted with neonatal hypoglycemia. The incidence of preeclampsia and other hypertensive disorders was 7%. There were no maternal or neonatal deaths in this cohort.

Women with suboptimal control had a statistically significant increase in birth weight greater than 4kg [OR-0.15 (0.03,0.76)], however no difference was found in other maternal and neonatal outcomes when compared with women with good control.

At postnatal follow up, 1% of the women had overt diabetes and 2% had impaired GTT.

Conclusion Only 60% of GDM achieved good glycaemic (based on HbA1C). The only significant outcome in suboptimally controlled women was birthweight > 4kg. 55% women with GDM were controlled with diet alone.
